[0.65.0] Modified the database schema to address DataStore2 behaviour

[Windows81]

If you're getting the following error:

Query error:
        INSERT INTO persistence
        (
            "scope",
            "target",
            "key",
            "type",
            "value"
        )
        VALUES (?, ?, ?, ?, ?)

...

table persistence has no column named type

You have the following two options:

1. If familiar with SQlite, modify the persistence table to include a new column type of type TEXT NOT NULL.
   • The composite primary key used to be: scope, target, key
   • That primary key is now made up of: scope, target, key, type

CREATE TABLE "sqlb_temp_table_1" (
	"scope" TEXT NOT NULL,
	"type" TEXT NOT NULL DEFAULT 'standard',
	"target" TEXT NOT NULL,
	"key" TEXT NOT NULL,
	"value" TEXT,
	PRIMARY KEY("scope","target","key","type") ON CONFLICT REPLACE
);
INSERT INTO "sqlb_temp_table_1" ("key","scope","target","value") SELECT "key","scope","target","value" FROM "persistence";
DROP TABLE "persistence";
ALTER TABLE "sqlb_temp_table_1" RENAME TO "persistence";

2. Otherwise, clear the entire .sqlite database file.

Why did I make this change?

In Rōblox, ordered data stores of the same name do not collide with unordered data stores.

Versions of RFD prior to 0.65.0 made it so that DataStoreService:GetOrderedDataStore("test") would access the same data as DataStoreService:GetDataStore("test"). This was wrong behaviour and would cause DataStore2 to break.

For example:
https://github.com/Kampfkarren/Roblox/blob/cc8fec7045b5db0ae2fb03f03f537ec6d028b5ba/DataStore2/SavingMethods/OrderedBackups.lua#L60

function OrderedBackups.new(dataStore2)
	local dataStoreKey = dataStore2.Name .. "/" .. dataStore2.UserId

	local info = {
		dataStore2 = dataStore2,
		dataStore = DataStoreService:GetDataStore(dataStoreKey),
		orderedDataStore = DataStoreService:GetOrderedDataStore(dataStoreKey),
	}

	return setmetatable(info, OrderedBackups)
end
